Hi,

Not a huge number of patches this time. Some notable new features
though:
- Glock stats gathering (v. useful for performance analysis)
- FITRIM ioctl support
- Sorting the ordered write list (big performance increase when the workload
doesn't result in the write requests being nicely ordered to start with)

Plus a few clean ups, and bug fixes in addition,

Steve.
